United States Patent ENVELOPES Albert M. Broudy, Pittsburgh, Pa.

Application December 27, 1950, Serial No. 202,959

1 Claim. (Cl. 281-3) This invention relates to envelopes for incorporation in bound periodicals, magazines, trade or mail order catalogues, or like bound publications, for the convenient mailing use of prospective subscribers and purchasers, in response to the incorporated solicitations, and are somewhat of the type disclosed in my copending application for Letters Patent of the United States, bearing Serial Number 104,479, and filing date July 13, 1949, now abandoned.

Important objects and advantages of the invention are to provide a structure of the character described, which embodies an extension panel that may be increased in area to best meet conditions found in practice without increasing the size of the associated envelope and which extension panel need be folded together in one direction only to accommodate itself for insertion into the envelope, which displays all printed matter on one side only of the blank from which the structure is formed, which includes a partially visible sealing flap when bound into the periodical to apprise the user that an envelope is embodied in the structure, which is simple in its construction and arrangement, efficient in its use, and comparatively economical in its manufacture.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing, but it is to be understood that changes in the form, proportions, and details of construction may be resorted to that come within the scope of the claim hereunto appended.

In the drawing wherein like numerals of reference designate corresponding parts throughout the several views:

Figure l is a rear elevational view of an open formed envelope constructed in accordance with the invention.

Figure 2 is a plan view of the blank used in the formation of the envelope structure.

Figure 3 is a rear elevational view of a modified form of envelope.

Referring in detail to the drawing, denotes the entire integral paper blank from which the mailing structure is formed. The blank comprises a succession of three, rectangularly-shaped, connected panels, namely, the rear panel 1, the front panel 2 joined along a fold line 14 with the lower edge of the rear panel, and the extension panel 8 joined along an easy-tear line 9 with the upper edge of the rear panel.

The rear panel 1 and the front panel 2 are of uniform lengths, and in the formation of the envelope, said panels 1 and 2 are folded flatly against each other along the fold line 14, as shown in Figure 1. A gummed sealing flap 3 is formed at the upper free edge of the front panel 2, and a gummed end flap 4 is joined and extends coextensive with one end of the rear panel 1. A binding strip 10, adapted for side-stitch attachment in a bound publication, is joined and extends coextensive with the other ice endof the rear panel 1 and with the adjacent end of the extension panel 8, along an easy-tear line 11.

In the formation of the envelope, the end flap 4 is folded flatly against the inner end face of the rear panel I along the fold line 5, and the adjacent end ofthe front panel 2 is adhesively secured to thegummed face of said folded end flap 4. The other end of the front panel 2 is adhesively secured flatly against the adjacent end of the rear panel 1, inwardly of the binding strip 10, by means of a gummed area 7 extending along the inner end face of said front panel 2, as clearly illustrated in Figure 1.

Such connection of the ends of the panels 1 and 2 will provide an envelope pocket 16 of a length somewhat less than the length of the said panels themselves. The extension panel 8 is intended to be detached along the easytear lines 9 and 11 from the rear panel 1 and the binding strip 10, respectively, and to form an enclosure to be inserted into the pocket 16 of the envelope structure for mailing purposes.

The free end of the extension panel 8 is back set with respect to the adjacent end of the rear panel 1 to reduce the width of saidextension panel and thereby allow the latter, when detached and folded together crosswise only, to be accommodated in the reduced pocket 16 of the formed envelope.

The formed envelope is attached in the publication with the rear panel 1 thereof being disposed in front, as illustrated in Figure 1. Due to the back set free end of the extension panel 8, an end portion of the sealing flap 3 will be discernible and thereby apprise the observer that an envelope structure is embodied in the matter attached in the publication.

The modified form of the invention, shown in Figure 3, differs from the embodiment of the invention above described, only in that the envelope structure is joined along easy-tear lines 13 with a binding extension 12 of considerable width to allow the structure to be secured in the publication by the convention saddle stitch method instead of the side stitch method.

It will be obvious that, while maintaining the reduced uniform width of the extension panel 8, the latter may be varied as to length to any necessary extent to provide the surface area or space required for the purpose for which the mailing device is employed.

The blank 15 is preferably printed prior to its formation into envelope form. The surface of the front panel 2 displays the printed address of the promoter, while all other printed matter is on the extension panel 8 on the same side of the blank displaying said address.

The present invention provides a most efiicient mailing parcel generally conforming the conventional letter mail form, which entirely eliminates the compound folding arrangements of the wallet type mailing parcels now in use in bind-in matter for publications.

What I claim is:

A mailing parcel for binding into a bound printed publication comprising an integral paper blank having a succession of three rectangularly-shaped panels, there being a front panel a rear panel and an extension panel, said front and rear panels being substantially of uniform shape and size, the lower end of said front panel joined along a fold line to the lower end of said rear panel and folded flatly against the latter to form an envelope, a binding strip joined along an easy-tear line to one side end of said rear panel and the aligned side end of said extension panel, the side ends of said front and rear panels adjacent to said easy-tear line being flatly and adhesively secured together along said easy-tear line, the other side end of said rear panel carrying an end flap adhesively secured against the adjacent side end of said front panel, said front panel carrying a gummed sealing References Cited in the file of this patent flap extending along the upper end thereof, said exten- UNITED STATES PATENTS sion panel joined along an easy-tear line to the upper end of said rear panel, the free side end of said exten- 159L231 OHS g sion panel being back-set with respect'to the adjacent 5 2,0729 0 1938- side end of said rear panel to accommodate the recep- 2112'227 Ber owltz 1939 tion of said extension panel in the envelope when said 2'165195 Sawdon u y extension panel is detached from said rear panel and FOREIGN "PATENTS 7 said binding strip and to visibly expose a gummed sur 488,818 France 1918 face end of said sealing flap at said back-set end of said 10 extension panel.
